DIRIGIBLE LIGHT '2 SheetsSheet 2 Filed May 10, 1945 Fig. 5,

Imventor eson attorney 3 which is welded thereto and in use, the arm 29is disposed horizontally. The upper cleat 25 is similarly provided witha horizontally disposed arm 21, as shown in Figure 1.

The upper arm 21 is provided with an apertured bushing 28, the bore ofwhich is disposed at a right angle with respect to the arm 2'! and thebushing 29 of the lower arm 26 is similarly provided with a bore. Theabove mentioned pipe I!) extends through the bores of the bushings 28and 29.

As best shown in Figure 1, the threaded bushing M of the nut |3 restsupon the upper side of the bushing 29 of the arm 26 and the bushing M ofthe nut I2 abuts the lower surface of the upper bushing 28 of the upperarm 21. The bushing M of the nut rests upon the upper surface of thebushing 28 of the upper arm 21. The nuts l2 and I?) are compacted, asabove described, after the parts are fitted together in a manner wherebythe pipe H) is free to have horizontal turning movements. The pipe I isprevented from vertical sliding movement through the bushings 28 and 29by means of the nuts I I, I2 and I3.

As shown in Figure 1, the pipe ||l extends below the lower arm 26 and atthe lower end of the pipe H), a sleeve 30 is welded or otherwisesuitably secured thereto. Between the bushing 29. and the sleeve 30, acoiled spring 3| is disposed about the pipe ||l.

A collar 32 is slidably disposed on the pipe ||l below the spring 3|.The collar is provided with a set-screw 33 having wings 34, whereby theoperator may manipulate the set-screw for disposing the collar 32 in aselected position on the pipe H! for governing the tension or urge ofthe spring 3|.

The sleeve 39, at the lower end of the pipe I0, is provided with anoutwardly disposed arm portion 35, having a pivot-pin 36 which isemployed for attaching a lever-link 31 thereto. The lower end of thelever-link 31 is provided with a pin 38 for pivotally attaching anelongated lever 39 thereto.

A push-pull pipe 40 is employed having a lower end which is providedwith two outwardly disposed stub-pins 4|. The pins 4| are disposed ateach side of the pipe 40 and through the lever 39 for providing apivotal attachment between said lever and said pipe.

At times when the operator moves the lever 39 up or down, the push-pullpipe 40 is provided with a corresponding movement since the lever-link31 swings slightly on its pivot 36 to permit the same.

The sleeve 30, at the lower end of the pipe I0, is provided with aset-screw 42 having an inner end which bears against the push-pull pipe4!], whereby the operator may look the push-pull pipe 40 to the sleeve30 after he has made a suitable adjustment of the lever 39 forpreventing longitudinal movement of the pipe 4|] for purposes laterdescribed.

As best shown in Figure 1, the upper end of the outer pipe IE isprovided with screw threads 43, having a threaded engagement with acylindrical member 44.

The push-pull pipe 46 extends through the The bottom of the junction boxis provided with two oppositely disposed ears 46 and a bolt 41 extendsthrough and between the spaced-apart ears 46. The bolt 41 provides apivotal mounting for a link 48, the latter extending downwardly andhaving a pivotal connection, by means of a pin 49, with a pair of arms50. The arms 50 are disposed one at each side of the cylindrical member44, being pivotally connected thereto by means of suitable keepers 5|,as shown in Figure 1.

It will be seen that at times when the handle of the lever 39 is movedupwardly, the push-pull pipe 40 is provided with a corresponding upwardmovement for raising the ears 46 and the junction box 45 upwardly. Saidupward movement applies an upward movement to the link 48 and to thoseends of the arms 50 which are pivotally connected to the link 48 forpurposes later described.

As best shown in Figure 4, the pin 49 not only provides a pivotalconnection between the link 48 and the arms 50, but also provides amounting for the U-shaped supports 52, respectively disposed at the endsof the pin 49 and between their respecial pairs of nuts 53 and 54, saidnuts being threadedly engaged with their respective ends of the pin 49for clamping the U-shaped members therebetween. The outer ends of theU-shaped members 52 each support an incandescent light socket 55.

Referring to Figure 1, the socket 55 is provided with oppositelydisposed pins 56 which extend through suitable apertures 51 providedthrough the outer ends of the arms of the U-shaped support for saidsocket. The pins 56 are provided with screw threads having threadedengagement with the wing-nuts 58 for locking the socket 55 to itssupport. The other socket is provided with the same arrangement ofthreaded studs and wing-nuts.

By manipulation of the wing-nuts 58, the sockets 55 may be disposed andmaintained in parallelism with each other or inclinedly with respect toeach other for causing the incandescent light bulbs 59 to converge theirrays of light upon a selected area. For normal use, said sockets aredisposed and maintained in approximate parallelism with respect to eachother.

As best shown in Figure 1, an insulated electric light cord 60 extendsthrough the push-pull pipe 40. The lower end of the cord is providedwith a push-in plug 6| having two electrodes 62 and 63. An insulator 64encircles the cord 60, being disposed against the lower end of thepush-pull pipe 40. The upper end of the cord 60 is bifurcated, wherebythe branch 65 of said cord extends to a socket 55 and the other branch66 extends to the other socket.

It will be seen that at times when the electrodes of the push-in plug 6|are engaged in an electrically energized receiver socket of anelectrical circuit that said energy is communicated through the cord 60to the sockets 55 respectively for correspondingly energizing thefilaments within the bulbs 59, whereby beams of light emanate from thetransparent envelopes of said bulbs 59.

In operation, the clamp 8 being secured to the wall or object l1 so thatthe hooks, 22 of the clamp converge upwardly and the upper clamp l9being disposed in position with its side walls converging downwardly,the other parts of the device being assembled as above described, theoperator then causes the upper cleat 25 to become engaged in its socketI9 and he then moves the 3| since the bushing 29 must be moveddownwardly for said purpose at this time.

Then the bushing 29, arm 26 and lower cleat 24 are released, therebypermitting the spring 3| to move the cleat 24 upwardly and intoengagement with its socket or clamp I8.

The set screw A is now employed for causing the bushing 29 to becomelocked to the outer pipe H] at desired times, whereupon the device is inoperative position and it will be seen that the device may be readilymoved from one location to another as may be desired, provided each newlocation is equipped with further clamps like the clamps l8 and I9, saidduplicate further clamps being secured to the side walls of selectedbuildings, trees, posts or the like.

In order to move the device from one location to another, the set screwA is released and the arm 26 moved downwardly, against the urge of thespring 3 E for releasing its cleat 24 from the the lower clamp l8,whereupon the device may be moved upwardly for releasing the upper cleat25 from its holder or clamp l9.

At times when the new device is in position, as shown in Figure 1, andat times when the setscrew 42 is released, the lever 39 may bemanipulated for causing the sockets 55 to be swung in verticaldirections and to a selected position, simultaneously the set screw Abeing released, the lever 39 may be manipulated for turning the sockets55 in a horizontal direction until the beams of light from the lightbulbs 59 converge upon work such as a pile of wood to be chopped or thelike. At times when the set screws A and 42 are disposed inwardlysufiiciently, the sockets 55 are not movable vertically or horizontally.

From the foregoing description, it is thought to be obvious that adirigible light constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason, I do not wish to be understood as limiting myselfto the precise arrangement and formation of the several parts hereinshown in carrying out my invention in practice, except as claimed.
